[Wien] lapw0_mpi hangs

Dear Wien2k,

I have compiled parallel wien2k in a following environment: (intel11
and openmpi1.4.3)
 Currently Loaded Modulefiles:
  1) gcc/4.4.3                      5) openmpi/1.4.3
  2) binutils/2.20                  6) PrgEnv-intel/11.1.064
  3) intel/11.1.064
  4) acml/ifort/4.3.0

Problem is that parallel version of lapw0 (that is lapw0_mpi) produces
about 92% of the output compared to the serial version
(files case.output0000 and case.output0)
and thereafter nothing happens (though CPU time runs and processes are alive).
Serial lapw0 runs in 2 minutes and a 4 prosessor parallel job does not
finish in one hour.
The first MISSING line in the parallel output file is:
 SELECTED FOURIERCOEFF. OF V-XC


I'm happy to provide more info, but really don't know howto proceed here.
Files I get are:

 lapw0.error has contents:
Error in LAPW0


There also seems to be some memory problems with lapw1... But hope to
settle lapw0 first.

Terveisin, Markus
